A designer builds a model of a sailboat. The finished model is exactly the same shape as the original, but smaller. The scale factor is 2/15 . (a) Find the ratio of the volume of the model to the volume of the original.
(b) Find the ratio of the surface area of the model to the surface area of the original. (C)Find the ratio of the width of the model to the width of the original.
Write these ratios in the format m:n.

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
